FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60695-2-11 has been prepared by IEC technical committee 89:
Fire hazard testing.
The text of this standard is based on the following documents:
FDIS Report on voting
89/1197/FDIS 89/1206/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
It has the status of a basic safety publication in accordance with IEC Guide 104 and

This standard is to be used in conjunction with IEC 60695-2-10.
This second edition of IEC 60695-2-11 cancels and replaces the first edition of
IEC 60695-2-11 published in 2000. It constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– The Introduction has been added to provide background and how it relates to the Scope.
– The Scope has been modified for greater clarity and reference to basic safety
publications.
– Numerous terms and definitions relevant to this Standard have been added to Clause 3.
– The application of “small parts” and “insignificant mass” have been introduced and
clarified.
– The different types of specimens, how to specify them, and limitations of the test method
have been further clarified in Clause 4.
– Clarified in Clause 5 the distance to specified layer when unknown.
– The information from Clause 6 has been moved into the test procedure in Clause 8.
– The conditioning of the specified layer and the laboratory ambient test conditions were
clarified in Clause 7.
– Measurement of the maximum flame height was removed from Clause 9.
– The reference to this test as “GWEPT” was introduced along with an applicable title
change.
– Annex A has been revised to reflect current practice by prominent product committees.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
The purpose of this Introduction is to provide background regarding the basic guidance that
prompted the preparation of this International Standard and how it relates to the Scope.
In the design of any electrotechnical product, the risk of fire and the potential hazards
associated with fire need to be considered. In this respect the objective within the design of
component, circuit, and product design, as well as the choice of the materials, is to reduce to
acceptable levels the potential risks of fire during normal operating conditions, reasonable
foreseeable abnormal use, malfunction, and/or failure. IEC Technical Committee 89 has
developed IEC 60695-1-10, together with its companion, IEC 60695-1-11, to provide guidance
on how this is to be accomplished.
The primary aims of IEC 60695-1-10 and IEC 60695-1-11 are to provide guidance on how:
a) to prevent ignition caused by an electrically energized component part, and
b) to confine any resulting fire within the bounds of the enclosure of the electrotechnical
product in the event of ignition.
Secondary aims of these documents include the minimization of any flame spread beyond the
product’s enclosure and the minimization of harmful effects of fire effluents such as heat,
smoke, toxicity and/or corrosivity.
Fires involving electrotechnical products can also be initiated from
